The principal object of the present inven- The set screws 8 afford means for bringing 65 tion is to provide for positioning structural the top 3 of the beam 5 into contact with the members, such as beams, and for holding bottom 1, of the clamp, and the set screws 7 them in position during welding. afiord means for adjusting the top 3 of the 5 Other objects will appearzfrom the followbeam 5 into line with the top f the beam ing description'atfthe end of which the 1n- 6. It will be understood that when the co ti ill b l i d, v .bcams.are in the position shown they can be Generally stated, the invention compr ses readily welded as indicated at 10, and furva clamp for positioning and holding beams ther that they can be readily broughtinto.

1 consisting of two members bolted together that position. As shown the clamp com-' and having atone of their ends set screws prlsestwo members 11 and 12, which are for resting upon the top ofione beam and slmilar except that one is righthanded and having intermediate of their' lengths U- the other is lefthanded. These members are shaped jaws adapted to receive the flange of connected by bolts 13, and they are shown as 15 another beam and provided ,withset screws flanged both marginally and crosswise at the for bringing the top of the last nientioned aws 9. These'elements, as indicated in the beam level with the bottomsurface provided drawing, are provided at one end with lath ber to constitutesa'id ends in eral extensions in which the set screws or eflfect a prolongation of'the top. ;of. the last bolts 7 are mounted, and in "this way a wide 20 mentioned beam. I base is provided for supporting the clamp The invention also comprises the improveupon' the-beam 6. ments to be presently describedfand finally It will be obvious. to those skilled in the claimed. i j I art towhich the invention relates that modi- In the following description reference will fications maybe made in details of construc- 25 be made to the accompanying drawing tion and arrangement and matters of mere forming part hereof and in which form without departing from thespirit of Figure 1 is a top or plan view of a clamp the invention which is not limited to-such embodying features of the invention show-, matters or otherwise than the prior art and g, the same in application to a couple of the appended claims may requirei 30 floor beams. v I I claim: p v Fig. 2 is an elevational view partly in sec- -1.

I A. A clamp for positioning and holding beams forwelding, a portion of one of said beams having the flange and a portion. of

k the web removed, the clamp having a hot tom surface conforming to the top surface ofa beam and having spaced from one end means for holding the top surface of the beam in contact with said bottom surface, the space between the said end of the clamp and said means and between the portion of saidbeam from which the flange and part' of the web have been removed being adapted to "receive the 'flange ofa second beam, and set screws at ,said' end of the clamp for bringing the top of the first mentioned beam flush-with the top of the last mentioned beam. 1 I 5 5; A clamp for positioning and holding beams for welding having a flat bottom sur-. face adapted to rest upon the top level siirfaces of two beams and having spaced from one end means for clamping the top surface ofone beamagainst a portion of the flat bottom surface of the clamp leaving the other portion of the .flat bottom surface of the clamp free tore'st upon the top surface of the other beam.

G. A clamp for. positioning and holding beams for welding having a flat bottom sinface adapted to rest upon the top level sur faces of' two beams and having spaced from one end set screws for clamping the top surface of one beam against a "portion of the fiat bottom. surface of the clamp leaving another portion of the fiat bottom surface of-the clamp free't'orestupon the top-surface of the other beam and having addi-- tional set screws disposed oppositely in respect to the first mentioned set screws and arranged at said end for resting upon the topsurface of the last mentioned beam.
